Python 3.7: RuntimeError: generator raised StopIteration

[scat25]

Using cppclean with Python 3.7 results in a RuntimeError for most of our Projects. It's probably a result of PEP 479: https://www.python.org/dev/peps/pep-0479/

Traceback (most recent call last):
  File "c:\program files\python37\lib\site-packages\cpp\ast.py", line 887, in _get_matching_char
    token = get_next_token()
  File "c:\program files\python37\lib\site-packages\cpp\ast.py", line 904, in _get_next_token
    return next(self.tokens)
StopIteration

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Program Files\Python37\Scripts\cppclean", line 166, in <module>
    sys.exit(main())

I had the same errors on classes that had some kind of export macro and are final at same time: class EXPORT_MACRO Foo final {}; I made a small PR (https://github.com/myint/cppclean/pull/152) to fix the issue. It works for me, maybe it also helps you.

[scat25]

It fixes some of the errors but not all

Sorry for the slow reply. Yes, I also have still some issues. I might look into them at some point. Meanwhile for me I just changed the code a bit to ignore the thrown RuntimeError, such that at least the remaining files are processed
